The Forensic Accountant's Playbook: Detecting Corporate Fraud

Occupational fraud is one of the most silent yet destructive threats a business can face. According to the Association of Certified Fraud Examiners (ACFE), organizations lose an average of 5% of their revenue to fraud each year.

The Fraud Triangle

To prevent fraud, we must understand the Fraud Triangle:

1. Pressure: A financial need or incentive (debt, addiction, greed).
2. Opportunity: A weakness in internal controls that allows the fraud to occur (lack of reviews, shared logins).
3. Rationalization: The cognitive justification for the act ("They don't pay me enough," "I'll pay it back").

Common Billing and Payroll Schemes

As a forensic investigator, the most common schemes I encounter include:

• Ghost Employees: Adding fake profiles to payroll and routing their wages to a conspirator's bank account.
• Shell Companies: Setting up fake vendor accounts and submitting fraudulent invoices for services never rendered.
• Expense Report Manipulation: Submitting duplicate receipts, personal expenses, or inflating mileage logs.

Designing Internal Controls (SOX 404)

The strongest deterrent to fraud is the segregation of duties. No single employee should have the authority to:

• Approve a vendor,
• Receive the vendor's invoice,
• And write the check.

Implement mandatory vacation policies and independent reconciliations to ensure irregularities are caught early.
